Patented Jan. 12, 1932 PATENT OFFlCE HEINZ KAHLHOFER, OF VIENNA, AUSTRIA APPARATUS FOR THE PRODUCTION OF HAIR WAVES Application filed January 3, 1930, Serial No. 418,369, and in Austria January 7, 1929.

The present invention relates to apparatus for the production of hair waves and has for its object apparatus of this kind in which the curler sheaths are heated by hot air.

It is usual in hair waving apparatus to produce the heat necessary for setting the waves in a separate piece of apparatus and to conduct the heat by means of pipes to the point at wnich'it is used. In permanent waving apparatus a number of curlers are used which are attached to a member usually suspended above the head of the subject.

This method is wasteful, as the air must be heated to a greater degree than is necessary due to the fact that it must be conducted some distance before it is used.

According to the presentinvention however, the hot air is produced in the individual air teed pipes which lead from an air distributor which is provided with a blower or like wind generator either inside the same or mounted directly on the outside thereof.

This is accomplished by means of electric heating bodies such as coils of resistance wire which are built into said air feed pipes.

The invention will now be described in conjunction with the accompanying drawings in which Figs. 1 and 3 show construction examples.

Figs. 2 and 4 show details in section.

Like reference numerals indicate like parts.

From the air distributor 1, branch of? air pipes 2 in which the electric heating bodies 3, are built, to the curler sheaths 4. As shown in Fig. 1, the heating bodies are preferably situated at the ends (at the left of the middle line) or at the beginning of the air pipes at the right of the middle line). The current wires 5 one for each heating body lead from the air distributor inside the air pipe to the curler sheaths 4 or alternatively they may be led along the outside of said air pipe.

According to Fig. 1, the blower or wind generator 6 is contained inside the air distributor, while in Fig. 2 it is attached directly on the outside of the housing of the air distributor by means 'of an outlet tube 6a so that the latter and the air distributor housing have a common imaginary axis.

The assembly of the air teed pipe is accomplished in such a manner that changes in the length h of the single air-feed pipes 85- are possible (Figs. I and 3) so that the curlers can be easily adapted to the shape of the head of the subject. This can be accomp'lished as shown in Fig. 3 by providing the lower wall of the air distributor with a guide m 7 in which a section of tube 2a is slidably attached to the air pipe 2 or, as shown in Fig. 4., by firmly fixing the air pipe in a guide 8 attached to the flange of the air I distributor. In order to keep the air pipes U which are not in use away from the head of the subject the books 9 are provided as shown in Fig. 1.

The main advantage of the invention consists in the fact that any number of curler sheaths may be heated in a short time with little consumption of current since the hot air is produced at the point where it is used, thus avoiding heat losses.

I claim 1. Permanent waving apparatus comprising in combination an air distributor, means for conducting air from said distributor to curling sheaths and electric heating means for heating the air, which are situated in said air conductingmeans near that end thereof which is adjacent to the curler sheaths.

2. Permanent waving apparatus comprising a blower secured to the air distributor housing, means for conducting air from said distributor to curling sheaths and electric heating means for heating the air, which are situated in said air conducting means near that end thereof which is adjacent to the curler sheaths.

3. Permanent waving apparatus comprising a blower, and air distributor, means comprising pipes for conducting the air from said distributor to curler sheaths, electrical means for heating the air, which are situated near that end thereof which is adjacent to the curler sheaths, said air conducting pipes being combined with tubes which are slid'ably attached to guides arranged in the lower wall of said air distributor, for the purpose of adapting the length of said pipes to the head of the subject.

4:. Permanent waving apparatus comprising' a'blower, an air distributor, air pipes for conducting the air to curling sheaths, means comprising electric heating bodies situated in said air pipes near that end thereof which is v adjacent to the curler sheaths, said air pipes being attached to the sides of the air dis- 10 tributor housing, means for holding said air pipes attached to the lower flange of said air distributor for the purpose of varying the length of said air pipes in order to adapt them to the head of the subject.

u 5. Permanent waving apparatus comprising a blower, an air distributor, air pipes for conducting the air to curler sheaths, means comprising electric heating bodies situated in said air conveyingpipes near that end therego of which is adjacent to the curler sheaths and means comprisinghooksl for the purpose of holding these air pipes which are not in use attached to the sides of said air distributor.

In testimony whereof I have hereunto af- 25 fixed my signature.

HEINZ KAHLHOFER.
